. This invention'relates in general to improvements in water closets and has more particular reference to the type of water closet in' use in railway cars and similar locations.

Toilets of this classare usually equipped with" a dump pan adapted to Lbevrocked downward in flushing, and with-a draft or sealing plate at a point below the dump pan, adap'tedto'prevent` up-draftthrough the 'toilet or closet. This invention has for a principallobject'the provision of mechanism for rocking the dump panVso connected with the draft platethat upon the return of the .dump pan to original position, the sealing A further object of the invention` is the proe` vision of mechanism permitting the adjustmentof the sealing plate in more or less distant relation to the lower end of the device, thereby permitting4 the sealing plate to b'e normallyl held in partly open position and preventing the-freezing ofthe plate to the lowerend ofthe device.

vision of mechanism ofthis character in which the sealingiplate is retained in its normal or closed position throughout the entire ymovement of the dump pan for the discharge of waste there-7" from, the sealing plate'being moved to open po`si` tion only duringl the return original position.

Another object of the invention is the provision of mechanism in which this opening movement plate also is back in its original position.'

A further important object of the invention'is the provision of mechanism of this character in which the connection between the dump pan and 'fthe sealing plate is effected by'linksunde'r control of a 'counterweight, means-being provided,

however, for preventing excess movement ofthe mechanism for actuating the dump pan'.

Numerousother objects and advantages ofthe invention will be understood from the followingldescription, which, when taken in connection with the accompanying drawings, discloses a preferred embodiment thereof; i Y

For the purpose of illustrating thepresent inwith the dump pan actuating mechanism and f vention, the 'drawings illustrate a closet of the A further object of the invention is the 'pr'o' character generally provided in railway cars." This closet comprisesa bowl 1` supported on a'v standV 2.'- 'A dump pan, indicated byf'reference character 3, normally closes the lower end of the bowl andis vix'edlymo'unted on a transverse shaft 4 extending through`r the stand 2 and is sup` ported in bearings A(not shown) which may be formed integral withthe stand.

Ani arm Vyxedlysecured. tothe shaft 4 atA one end,"is providedv withapin extending into aslot' 'I which is provided in the lower portionV of a link 8. I'he opposite end of the shaft f4 is equipped with an arm carrying at lits freeend av counte'rweightL 9 for* normallyv holding the dumpl pan 3.111 closed position,- as'shown in dotted lines insign;

The upper end of the-'link'S is pivotally con nected with a lever lhaving a handle 11 at one end andbeing connected at the other or fulcrum end with-a flushing valvev 12 ofV any preferred or desired construction, vso that upon raising the lever '10,the'movementof'the dump pan'3 to' ofthe open vposition isinitiatedwhile at the same time u the flushing valve'12 is set' in operation in order to thoroughly 'iiushfthe interior of the bowl. All of these parts are' of thel usual and well known construction, and are more particularly shown anddescribed in UnitedStates-'Letters Patentv v No`s`."1,'881,528; 1,845,252; 1,898,656 and 1,898,857.

The-shaftl, journalled-in bearings 17 of the 'i stand, carries an arm 20 xed at one end and an arm 21, loosely mounted thereon, having a bifurcated end, the prongs 22 of which serve for loosely supporting the arm 21 on the shaft 16. An extension 23 of the arm 21 is yieldably connected with the end of the xed arm 20 by a tension element in the form of spring'24.

A pin 25 projecting laterally from the arm 21 between its ends serves as; a pivotal support for a lever 26 which carries a weight 27 equipped at its lower portion with a knob `V28 of rubber or other suitable sound and shock absorbing material. ,Y .i

A nger 29 projecting upwardly from the lever 26 supports at its free end an adjusting element or screw 30 extending through avtapped opening of the nnger 29 against 'arllugor abutment 31 which projects laterally from the arm 2Q. 'A nut 32 on the screw 30 servesto hold the screw in adjusted position relatively to the finger 29 of lever 26.

The spring V24has a tendency to move the .arm 21 clockwise about the shaft 16, and the lever 26 resting with the Weight27 onthe iioor lor water closet supporting mediumv restrains this rocking movement. The engagement of the adjusting screw 30 with the `lug 3 1jof the arm 20 prevents anti-clockwise movement'of the arm 20. 4It will be apparent that the position lof the arm 20 relatively to the other parts may :be altered through the adjustmentr of this screw 30 to permit the sealing plate 14 to seal against the end Vof stand 2 as shown in Figs.` 1 and 8, or tobe spaced from its seat as shown in.1 .ig.v.2, in which last named position freezing of thesealing plate to the extension 13 of the stand 2 wouldbe prevented. The

sealing plate 14 A,is lfastened-rigidly to-the shafts,

Owing-ftothepin 3 5 being aboutv midway of the,` ,slot V34when the parts are position of rest (Fig. 1)-, the initial movement of .segment 19 will take place without influencing the weighted arm 26. At the end of the opening nfiovementofl the dump pan, however, the parts `assume the posi-` tion illustrated inFig; 3 wherein theangular link 33 ofthe segment 19 `'has caused the weighted lever 26 to swing upward about its pivot 25. j,During this movement the adjustingI `element 30 (which mayhave originallyheld the -draft plate 14 in sealed position (Fig. 1) or in spaced position (Fig. 2) has` moved away rfrom the abutment 31 ofA arm 20. If the draft plate is normally spaced, asshownin Fig. 2,-the arm 20 may have performed a rocking movementunder the .influence of a weight 42 on shaft 16` thereby bringing the plate 14 to sealing position, shownin Fig.` 3.

26 having -moved beyond its deadcenter position, Y

it wouldhave a tendency to continue this swingling @vement -Qourterqlockwisa This-action. ofy

the weighted lever 26, however, is prevented by the provision of an abutment or lug 36 projecting from the arm 21, and against which abutment the lower portion'of the lever 26 cornes to rest.

Upon release of the hand lever 11 after a dumping movement of the pan 3, the counterweight 9 on shaft 4 induces a return movement of the parts to the normal position.

A catch-37 is loosely pivoted at 38 on the inner face of thev weighted lever' 26, and this catch freely moves during the described swing of lever 26 over a lug 39 which projects from the arm 21 into thepath of said catch. It then rests loosely against the hub portion 40 of lever 26 which is supported on the pivot pin 25.

.In the returnfmovement of the parts from the position shown in Fig. 3, the segment 19 will swing in a counterclockwise direction about the shaft 4 and the angular link 33 will, after a certain initial idle movement, push against the weighted lever 26to swing it in av clockwisedire'ction about its pivot pin 25.

`During this return movement, the rim ofthe segment 19 rides overa roller 43 on the arm 21 vtok vhold this arm vdown against the action'of spring 24, and aftera certain part .of this return movement has been completed, the catch 37 en,- counters the projection 39V extending laterally.

from the arm 21. Further downward movement of the weighted lever 26 is thereby momentarily 26, and catch 37 ywhich will rapidly swing about the shaft 16. This movement of the arm 21 will betransmitted kthrough spring 24 to the larm 20.

connectedwith the sealing plate 14 and the latter, therefore, will be rocked awayfrom'normal position to the-position ofFig. 5.

, The; weight 27 inuences this movement of the arm 20 with considerable leverage..to effect an extensive swinging movement ofthe varm 20-and plate` 14` when. the knob A280i fthe weight 27; strikes the ground, so that the weight ceasesto influencek thearm 21. The sealing'plate 141is now in fully open position and the` arm 21 swung upward. -f f The counterweight 42, mounted on shaft 16',

will now swing `back to normal position (Fig, 5)

thereby also inducing the return movement of the arm 20, spring 24 and arm 21' to their original position. During .this return movement the shelf 31 on arm 20 again comes into contact with the lower `end of .the set screw 30, slightly' liftingv the weighted lever 26 and permitting the arm 21 to return to its original position A(Fig. 6). It is thought that the invention vand many `of its attendant advantages willbe understood fromy the foregoing description, and it will. beapparent f that .various changes may be made. inthe form, construction and arrangementof the parts without departing from the spirit and scope of the invention or sacrificing all ofl its 'material advantages, Vthe form hereinbefore 'described being merely a preferred embodiment'thereof.
